AUTGMATIC FUSE-RESETTER.

Losa/iii.

To all whom it may concern Be it known that I, JOHN B. Eutin, a citizen of the United States, and a resident oiColunibia, in the county oi Richland and State of South Carolina, have inade certain new and useful Improvements in Automatic Fuse-Resetters, of Which the following is a specification.

My invention relates to improvements in devices for automatically resetting fuses and it consists in the combinations, constructions, and arrangements herein described and claimed. y

The main object of niy invention is to provide a device to be used in connection with telegraph or telephone circuits i'or ren setting fuses which have been burned out by lightning. i

A further object of my invention is to provide a device for automatically resetting any number of fuses, thereby obviating the necessity of setting the device after each op eration, preparatory to the next operation.

A further object of my invention is to vprovide a novel device having certain inn provernents over that disclosed in my prior Patent #1,018,239.

Y @ther objects and advantages will appear in the -following specilication and the novel features of the device Will be particularly pointed out in the appended claires.

My invention is illustrated in the accom-n panying drawings forming part of this ap plication in which similar reference charactors indicate like parts in the several views Figure 1 is a plan view of the device, Fig. 2 is a vievv similar to Fig.. 'l showing the parts in a shifted position7 certain portions being broken away for the sake of clearness, Fig. 3 is a side view of the device certain parts being shown in section, Fig. i is a section along the.line 4-4 of Fig. l, Fig. 5 is a section along the line 5--5 of Fig. 2, Fig.

6 is a. section along the line 6--6 of Fig. l, and Fig. 7 is a view of detail parts of the device.

In carrying-out my invention I provide a base l upon which is mounted the binding posts 2 and 3, the rcel support 4, the brush supports 5 and and the cleaner arm supports 7. At S is a casing which is secured by means of screw bolts 9, Washers 1.0 being disposed between the casing and the base l.

a shaft l0. A spring il has one end las tened to the shaft l0 and the other end to Iunn ediatcly above the spring ll is a plate or dish l2 `which is secured to the hub ot a ratchet wheel i3, the latter being keyed to the shaft l0. `Above the ratchet Wheel is an escapement Wheel le, which is secured to a hub or head lloosely mounted on the shaft l0. The Wheel lei. bears aclp 16 arranged to engage the teeth of the ratchet I3. Secured to the head i5 by means of screws l? is an insu lated plate i8. rIhis plate is ci oblong shape, as shown in Figs. l and 2 and has mounted upon it at each end' a metal block 'i9 like that shown in Figs. 5 and 27. ihc block is provided with a'central recess lx arranged to receive a spring 2O (see Fig. o). A locking plate 2l like that shown in is provided with ears which entend into recesses 19 of the block i9. The locking plate 2l is pivctally held to the bloei; li by ineans of pins such as that shouf'n at in Fig. 5, which pass through the openings in the ears 22. The locking plat l also provided with an extension 2lb which passes through an opening 18 in the plate i8. Carried by the casing El is a crescentshap .l cam 24 which is arranged to engage the extension 2lb of the plate 2l to force this part toward the block il@ against the tension oi' the spring 20, thereby lifting the plate 2l 525 'which th 2l clamps against the bl :lr 1 9, as vri plained later.

Referring particularly tol Figs. 2 and 3, I have shown a shaft E2G which is journaled in the casing 8, and which is provided with an escapenient 2? (sce l? 2 arranged 'to engage the escapenient Wheel 14. The un per end of this shaft is provided with an arm 28, which bears at its outer extremity an insulating stop member 2S?. The plate 2l is provided with an opening 2l through which the end 'of an S-shaped stop rnenilier 30 extends. This stop member 30 is pivot- I ally mounted in an opening 19Z in thebloclt 19 and the opening 2]. in the plate 21 is large enough to permit the pivotal niovenient of the plate 2l on its pivots 23 without interfering vwith the :n.ovcnient ofthe stop member 3G.

As will be seen. from the drawing-s the plate 18 has a block 19 and its associsdte plate 2l, and stop member 3() at cach end.

The stop member 8O is provided with an insulating tube 3l at its end arranged to en-v gage the fuse Wire 25. The fuse Wire 25 is carried on a shoulder 32 mounted on the support 4. A spring 33 bears at one end on a rod 34 which passes through the post Li, as shown in Fig'. 6, the outer end ot' a rod forming a guide eye 34.- through which the fuse wire passes. A plate' 35 receives pressure from the spring 33 and the wire is held between this plate 35 and a plate 36, the latter being secured to the post by means of a thumb nut 37. The spring 3B is for the purpose of supplying suiiicient tension resistance to prevent the unwinding of the reel 32.

From the foregoing description of the various parts of the device the ooeration thereyof mav be readily understood.

ln setting the device the wire is passed through the guide 34; '(see Fig. l) and a portion of it is placed between one of the plates 2i and its associate block i9, the plate being lifted against the tension of the spring 2Q so that when the of the fuse wire 1s placed underneath the. plate it will spring' down upon it and clamp it. It .now the stem or shaft l is wound thespring ll will be tightened. lWhen pressure is relieved from ythe stem l0 the spring will vcause the rotation of the escapement wheel le, which will be regulated by the Iescapement 27, the larm 28 vibrating lto and fro. 'The plate i8 will rotate in the direction shown by the arrows in l. As the 'plate 21, opposite the end which is now grippingthe fuse Wire,

reaches the cam 2d tne engagement of the tension :2lb will open the p ate to receive a Vportion ofthe fuse Wire 25 whenthe plate comes around in position to receive it. When it passes oil' from the cam a portion of the fuse wire will be held between two plat-es. .its the plate revolves however that .portion of the inse wire which. is held between the two plates comes in contact with the stopmember 3) and pushes this stop member into the path of the insulatin block 29 on the erm 28, thereby holding t ie arm and preventin the further rotation of the 5g; `device sincet e escapement 27 cannot 0pcrate unless the arm 28 and the block 29 are in vibration. The apparatus is now set Jier work. y

The line wires 58 and 39 are secured to ne the binding posts Qand 3 respectively; Current will pass from the 'wlre 38, through .binding post 2, post 5, brush 40, conducting' block i9, fuse wire 25, conducting block 19 von the opposite side, brush Lll, post 6, binda0 ing post 3 to wire 3a, lf now a rush of curshould occur the use wire will burn out between the two clamping 'members y 2i. This willaperinit the bloeit Qclwhich is uno5 (lentils tensionzof the escapementwlieel to,

caused Vby lightning noeaaiv vibrate back and forth, the stop member being moved out of the Way. The plate i8 will new rotate, and when the plate 2l which is now openpasses the spring scraper or brush 42, the latter Will clean out any unburned wire between the plate and the block 19. As the plate continues to revolve the wire 2 5 will be drawn in between the plate and the block i9 and when the extension 2lb of the plate passes oli from the cam Qd the spring 2O will cause. the plate to grip the Wire as before described. As the fuse Wire which is held between the two gripping' plates 2 again comes into engagement with the stop member 30, it will be forced against the block 29 so as to stop the vibration of the latter and hence will stop the rotation of the plate. lt will thus be seen that the number of fuses which may be blown in succession and immediately replaced Will depend merely upon the capacity of the Wire. When once set up the device requires' no further attention, but is abs0- lutely automatic and will reset the fuses as fast as they are blown out.
